Thanks guys for the insight,will definately check power to the unit, guess i just seen all the corrosion thru the lens and assume it was toast as well as the VTS, which should be here tomorrow,did someone say the speedo was hooked into the VTS harness? maybe with New VTS working it will give me powert to speedo if thats the case.Did check the Paddle wheel, seen one tooth missing, assumed it was the one with magnet, nope, all 4 have magnet according to the little washer that came in the replacement pkg,so much for the cheap $50 fix, oh well, it needed it anyways.Next step, hook up the vts, check speedo with compressed air spinning the wheel, i assume tether switch needs to be ON? for speedo to work?
